Modeling Data

Baseline Cases

In developing the Regional Transmission Expansion Plan (RTEP), PJM annually performs comprehensive power flow, short circuit and stability analyses. These assess the impacts of forecasted firm loads, firm imports from and exports to neighboring systems, existing generation and transmission assets, and anticipated new generation and transmission facilities. PJM conducts a comprehensive assessment of the ability of the PJM system to meet all applicable reliability planning criteria.

Queue Base Cases

A key component of PJM’s RTEP process is the assessment of queued generation interconnection requests and the development of transmission upgrade plans to resolve reliability criteria violations. This interconnection assessment ensures the initial deliverability of the respective request. Thereafter, the PJM RTEP process annually completes studies that reveal any transmission expansion upgrades needed to ensure the ongoing deliverability of all generators within PJM.

MOD-032 Modeling Data

NERC’s MOD-032-1 standard’s purpose is to establish consistent modeling data requirements and reporting procedures for development of planning horizon cases necessary to support analysis of the reliability of the interconnected transmission system. The standard requires PJM to develop data requirements, reporting procedures and schedules for the transmission owners, generation owners and other stakeholders in its footprint to support the building of steady state, dynamics and short circuit models. These models will then be passed along to the NERC designee to support building interconnection wide models.
